These breakfast bars blend juicy blueberries with hearty oats for a truly satisfying morning treat. The soft base holds sweet berries while the crunchy top gives you that amazing texture difference everyone loves.
Must-Have Ingredients
- Old-fashioned oats: Gives that wonderful chewy bite
- All-purpose flour: Makes the base nice and soft
- Brown sugar: Brings moisture and sweet caramel flavor
- Butter: Go for European-style for richer taste
- Fresh blueberries: Try wild ones for bigger flavor punch
- Cornstarch: Helps berry juice thicken up
- Vanilla: Get pure extract for best results
- Cinnamon: Adds that cozy spice touch
Instructions
- Oven Preparation
- Put your rack in the middle. Heat to 375°F. Line your pan with parchment and leave some hanging over the sides.
- Base Mixture
- Mix your oats, flour, brown sugar, baking soda and salt in a big bowl. Stir it all up good.
- Butter Integration
- Drizzle your melted butter and vanilla over everything dry. Mix until it looks crumbly.
- Bottom Layer
- Push half your mixture down hard into your lined pan. Make sure it's the same thickness everywhere.
- Berry Layer
- Toss blueberries with sugar and cornstarch. Spread them evenly on your base.
- Crumble Topping
- Scatter the rest of your oat mix over the berries. Press down lightly so it sticks.
- Baking Process
- Cook for 35-40 minutes until it looks golden and you see bubbling berries.
- Cooling Period
- Let it cool all the way in the pan. Use the parchment to lift it out. Cut with a sharp knife.

Kitchen Tips
Use parchment with the non-stick side down, try dental floss for clean cuts, stick a toothpick in to check if it's done, and turn your pan around halfway through baking.
Storage Solutions
They'll last 3 days on your counter, a week in your fridge, or 3 months frozen. Just let them thaw overnight in the fridge.
Nutritional Benefits
The oats pack lots of fiber for good digestion, blueberries give you antioxidants, whole grains keep your energy up, and you get natural sweetness from the fruit.
Seasonal Adaptations
Try mixed berries with lemon zest in summer, chunks of apple with extra cinnamon for fall, dried cranberries during winter, and fresh strawberries in spring.
Perfect Pairing Ideas
For breakfast, eat with Greek yogurt. As a snack, wash down with almond milk. Make it dessert with vanilla ice cream on top. At brunch, serve alongside a fruit smoothie.
